Public awareness refers to the knowledge and understanding that people have about a particular issue or topic. It is the extent to which individuals, groups, or society as a whole are informed and educated about something. Public awareness campaigns aim to educate the public on important issues such as health, safety, social causes, environmental concerns, etc., in order to promote understanding, change behavior, and encourage action. The more people know about an issue, the greater the likelihood that they will take steps towards addressing it or supporting those affected by it.
